GB 7300-2017Feed additive - Nicotinic acidacid (English PDF)

Foreword

The first chapter of this standard, Chapter 3 and Chapter 5 is mandatory, the rest are recommended. This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 7300-2006 "feed additive niacin." This standard compared with GB/T 7300-2006, the main technical differences are as follows:

--- Removed the determination of niacin content

--- High Performance Liquid Chromatography (second method);

--- Revised "heavy metals" test method;

--- Revised "Loss on drying" test method;

--- Increase the "total arsenic" limited requirements and testing methods;

--- Revised "shelf life." This standard is proposed and managed by the National Feed Industry Standardization Technical Committee (SAC/TC76). This standard was drafted unit. Shanghai Veterinary Drug Feed Testing Institute, China Feed Industry Association, Zhejiang Feed Supervision. The main drafters of this standard. Cao Ying, Huang Shixin, Ding Jian, Hua Xian Hui, Zhu Cong Ying, Huang Juan, Jiang Yin, Zhang Wengang. This standard replaces the standards previously issued as.
